PERRY BROWN, OF CORAQPOLIS, PENNSYLVANIA.

Toallwhomitmayconcern: I

Be it known that- I, PERRY BRow-N, a citizen of the United States, and a resident of Coraopolis, in thecountyof Allegheny and- State of Pennsylvania, have invented certain new. and useful Improvements in In the drawings accompanying and forming part hereof: Figure 1 is a front elevation of a brake made in accord nce with my invention, parts being broken away. Fig. 2 is a vertical central section of the same. Fig.3 is a perspective view ofthe Fig. #l is a perspective view of thecasing detachd.

,Referringnow to the details-of the drawv ingsby numerals: 5O designates a .casing having lugs 70 preferably cast integrally therewith which afford a means by which 3 the casing may be secured to a car by suitable bolts, as seen in Figs, 1 and 2. The casing is preferably open atthe front and is provided with a' divisional wall 51 having a central aperture 52. The back wall .58 ofthe casing is preferably provided with a similar aperture 5-1 and these two apertures 52 and 5% provide bearings for annular members 55 and 56 formed on a drum 57, this drum having ratchet teeth 58 preferably cast integrally therewith. The construction is such that the. drum 57 with its ratchet teeth may be inserted into position through the open front end until the mem-' bers and 56 are in position in the apertures 52 and 54. At the front end of the casing I provide a cover 60 and a bolt 61 passes through the cover and through an opening in the drum 57 audits integral ratchet 58, a nut 2 being provided on the rear end'of the bolt to lock the various parts together. A brake chain 63 is secured to the drum 57- in any desirable way, preferably by a bolt 64. The aforesaid casing 50 has an opening 71 in itsperiphery, and a dog 72 projecting from auweighted handle '74 enters the' casing an d 'co-acts withthe teeth on the "ratchet ,wheelfiS,this-dog and Specification of Letters ?a'ten-ti Application-filed November 22, 1915.

handle bein pivot-ally supportedby pin 26. The ido g'TQ' therefore holds the ratchet wheel from, counter-rotation and yet perm mits tlie ratchet wheel to move tooth by 60 tooth as it'is rotated.

Supported on the fbolt or axle pin" 61, preferably alongside of the ratchet wheel 58, is a link 30 which may be identical with the link shown in my aforesaid application Ser. No. 10,785 and therefore has a pin or stud 32' upon which is supported the op erating handle or lever 3 5. \This lever or a handle also may be identical with that shown in my aforesaid application and therefore has a pawl 36 adapted toengage the teeth of the ratchet wheel 58 so that when the handle or lever 34 is moved on the pin or stud 32 the first action is to cause the pawl 36 to engage the teeth of the 76 ratchet wheel 58.

Further movement of the handle or lever will cause the pawl 36' and its link 30 to swing upon the bolt or pin 61 and therefore rotate the ratchet wheel and the drum 57. A said application, the upper end of the handle or lever 34 is provided with a curved 'arm 40 which is substantiallyofthe same curvature .asthe inside of" the casing50.

The casing fiOlias an opening lQforthe purpose of allowing thehandle orleve1p3-1 ,to be moved upwardly to rotate the ratchet Wheel 58 and them-um 57, and when the, handle or lever 3% is permitted to drop to the vertical position shown in Fig. 1, the aforesaid arm 40 closes'the opening 42 and thus prevents'water or snowfrom entering the caslng. The interior of the casing 50 is provided with an interior lug or .flafn'ge 65 under which the end of the armflO :of the operating handle 34 projects sothat the various parts are properly heldin position.

In operation, the. brakeman grasps the handle or lever. Elland moves it up and 1 down in very much the samegwaythat an old fashioned pump would beoperated. On

the upward movement of the handle, the pawl 36 immediately engages one of the "ratchet teeth of the ratchet wheel 58, and

the handle swinging upon the link 30 causes the ratchet wheel torotate. Inasmuch as the ratchet Wheel and the drum move to-v gether, the'drum is rotated to wind up the .Chfllll 63and thus apply the brake. If one upward movement of the handle or' lever 342 is insufficient to apply the brake, the

handle is allowed to. drop by gravity to the As in my afore '80 operated from said drum, a casing inclosing said drum and having two vertical walls provided with bearings for said drum. a ratchet wheel rotatable with said drum, and a lever or handle supported in working relation to said ratchet wheel and arranged to drop by gravity to av substantially vertical position to release said ratchet wheel and drum and to co-act with said ratchet to rotate it and the drum when the handle is moved upwardly.
